Welcome to the Oregon Forest Pest Detector course final quiz. There are 25 multiple-choice quiz questions. You must correctly answer at least 80% of the questions (or 20 correct out of 25) to pass the quiz and the online course. The quiz may be taken an unlimited number of times.
Please complete the following information:
During which seasons are you most likely to see an adult ALB in Oregon?
late-spring to mid-fall
late-summer to mid-winter
late-winter to mid-summer
The most likely time of year that EAB adults would be active in Oregon is:
March - April
April - May
June - July
August - September
Which picture shows an adult EAB?
Which is NOT a defining characteristic of an invasive species?
Cannot be controlled with pesticides
Outcompete other organisms
High reproduction rates
None of the above
What is the main reason that it is difficult to control EAB?
The adult insects can fly very long distances
Symptoms of early infestation can be very hard to detect
No animals eat EAB because they are toxic
The insects live a long time
Which ash species are we most concerned about if EAB were to be introduced in Oregon?
White ash (Fraxinus americana)
Flowering ash (Fraxinus ornus)
Oregon ash (Fraxinus latifolia)
Green ash (Fraxinus pennsylvanica)
In which of the following scenarios would you feel it is NOT appropriate to report EAB or ALB?
You collect an insect specimen that looks like ALB. You compare this specimen to the look-alikes in Oregon. It does not appear to be any of the look-alikes.
You are driving in the country and notice a stand of unhealthy Oregon ash. You do not stop but you make a mental note of where the stand is located so you can report it later.
Using your binoculars, you notice what looks like D-shaped exit holes on the upper branches of an unhealthy ash tree in the woods behind your house. You also notice epicormic shoots stemming from the lower trunk. You collect a branch from the tree and confirm that it is an ash.
You notice a large amount of frass on the branches of a horsechestnut outside of your local community center. Upon closer inspection, you find round exit holes that are slightly smaller than a dime.
Which insect bores tunnels deep into the wood (or xylem) of host trees?
Which of the following is a characteristic of ash trees?
Leaves have 9 or more leaflets
Leaves and branches are opposite
Seeds are winged (samaras) and hang in pairs
Which picture does NOT show ash leaves?
Which agencies are responsible for preventing and managing EAB and ALB in Oregon?
Oregon Department of Forestry (ODF)
Animal and Plant Health Inspection Service (APHIS)
Oregon Department of Agriculture (ODA)
All of the above
If you think you see signs or symptoms of an EAB or ALB infestation, where should you report?
Call your local newspaper
Go to OregonInvasivesHotline.org
Do not report because it is likely to be a false alarm
Which photo shows galleries made by EAB larvae?
Which EAB life stage does the most damage to the tree?
Which pictures shows an adult ALB?
EAB was first found in the US in which state?
The genus that ash belongs to is:
Which of the following images does NOT show potential ALB damage?
What does EDRR stand for?
Early Detection and Rapid Response
Efficient Detection and Rapid Revegetation
Exotic Disease Response and Removal
Early Detection and Rapid Removal
Which of the following is NOT a typical sign/symptom of EAB?
Woodpecker damage (stripping away the bark of the tree)
D-shaped exit holes that are 1/8-inch in diameter
Epicormic branches (shoots coming from the trunk of the tree)
Sap oozing from the trunk
Which of the following is NOT a typical sign/symptom of ALB?
Crown dieback and broken branches
Round, dime-sized exit holes
Bark with a burned appearance
Chewed bark at egg sites

Detailed location information (such that someone could easily find the site and tree in question)
Detailed description of your observations (including the specific signs and symptoms that you observed)
The name of the property owner
